So I pose to ye, fellow scummy forum delvers; beautiful you all are anyway, what was the most satisfying religious discussion you've had with your opposing side? Be that any theist v and atheist or even just between someone of a different religious persuasion than you.

I would offer a personal anecdote to start this off, but I don't think I've had enough discussions yet to even quantify a 'best' yet, though rest assured if I have, it's been here.
